This campaign idea is very worthy. There are almost no legal restrictions on the use of these bird scaring devices and the volume at which they operate is outrageous. They are used primarily to deter pigeons but they will also be disturbing nesting birds of all species, especially the shy and sensitive farmland birds which are in decline, so there should be a ban on their use during the nesting season, at the very least. The psychological damage caused to residents within earshot of these devices is unacceptable and examples of comments from those affected can be seen on the National Farmers Union feedback page at http://www.nfuonline.com/News/Download-our-bird-scarer-guide/ The majority of farmers successfully grow their crops without using audible scarers so it is clear that there are alternatives and that these devices are not essential. I hope we can get a campaign going for the sake of all affected.
